KHS & Eckes-Granini launch bottles made of 100% rPET

Eckes-Granini hohes C PET juice bottles

Eckes-Granini is making its packaging portfolio even more environmentally friendly with the help of the KHS Grouping . Since the heart of May, its one-liter hohes C juice bottle has consisted entirely of recycled plastic (rPET) .

KHS' bottles & shapes experts in Hamburg were responsible for the optimization of the bottle. The new containers volition continue to be produced on the tried-and-tested InnoPET FreshSafe block . With KHS as its long-term partner, Europe's leading fruit juice producer is making a farther relevant contribution to expanding the round economy .

Eckes-Granini has been using 25% rPET in its hohes C PET juice bottles since 2018. "Bearing the Eu's plastic strategy in mind and the increase in recyclate quotas this prescribes, nosotros've at present decided to switch to using recycled PET simply. We want to be a pioneer equally regards the circular economy and set a good instance for the drinkable manufacture," states Hermann Naumann , found manager for Eckes-Granini in Bad Fallingbostel in Lower Saxony.

Europe's leading producer of fruit juice beverages has pursued an aggressive sustainability strategy for years, Naumann continues. "Nosotros aim to continue steadily reducing our carbon footprint in production and in our packaging. This means non only cutting downward on the amount of material used only too closing the recycling loop."

4,000 tons of new plastic and 8,000 tons of CO2 saved at Eckes-Granini

These are the exact problems KHS addressed kickoff when implementing the current project. With its holistic Bottles & Shapes consultancy program , customers benefit from over 40 years of expertise in container design and production. Here, potable producers state their preferences regarding the weight, shape, or stability of the container, for instance, upon which the system'southward supplier assesses the feasibility of the design with the assistance of laboratory tests and simulation.

In the case of Eckes-Granini, the specifications were articulate: switch to 100% rPET while maintaining the homogeneous quality of the container. According to Eckes-Granini, the changeover of the one-liter hohes C bottle to rPET will save over iv,000 metric tons of new PET per annum. This, in turn, means that the bottler volition cutting its carbon emissions by almost 8,000 tons a year.

Efficient and sustainable: KHS InnoPET FreshSafe block

Finding ways of saving on resources was not the only focus of the aggressive project. The ability to do and so on the KHS InnoPET FreshSafe cake in performance at Eckes-Granini since 2022 likewise had to be investigated. "One of the concerns was whether either the preforms or machine needed adapting," explains Dr. Matthias Kruse , head of PET Technology at KHS. "Nosotros thus assessed the quality of the recycled PET material. This is crucial, for large variances in color, molecular length, and inhomogeneity quickly reduce production efficiency."

The fact that Eckes-Granini procures its preforms from ii dissimilar suppliers presented an added claiming, Kruse adds. The preform geometry is essential for efficient processing, especially when a loftier percentage of rPET is used. Through all-encompassing testing, it was established that both makes of preform role soundly on the cake system. All that was needed for optimum bottle production were minor adjustments to the heater on the stretch blow molder.

KHS' NIR or near infrared technology especially provides a wide processing window for rPET, allowing preforms to be heated prior to the stretch blow molding process with pinpoint accuracy, for example. Every bit a result, no major changes to the machinery or geometrical properties of the preforms were required. "This enabled us to accomplish a very high level of process efficiency while retaining the container quality, thus fully coming together our customer'southward requirements," Kruse smiles.

rPET bottle too has barrier properties

Eckes-Granini volition continue to do good from FreshSafe PET bulwark protection also later on converting to 100% rPET. The company has relied on the environmentally-friendly system from KHS since 2006. The oxygen bulwark of chemically pure glass, a wafer-thin coating on the inside of the PET canteen, non only effectively protects the juice from oxygen pickup but is besides fully recyclable.

The coating can be easily washed off Eckes-Granini bottles during the recycling process. The sustainable packaging alternative, therefore, permits pure-grade bottle-to-canteen recycling. "By combining rPET and hereafter-proof product protection, Eckes-Granini and KHS are again demonstrating their pioneering office for the circular economy," claims Kruse.

Furthermore, past the stop of 2022, Eckes-Granini Deutschland intends only to use PET bottles made entirely of rPET for all brands, saving approximately 9,000 metric tons of new plastic per yr by doing so. Partner KHS is simply also pleased to aid.
